I UNITED STATES CHARLESTON, OF VANCOUVER, BRITISH COLUMBIA, CANADA.

STAMP-OPERATING DEVICE.

Application filed March 27, 1924. Serial No. 702,210.

To all whom it may Concern Be it known that I, MACE E. CHARLESTON, acitizen of'the United States, residing at Vancouver, in the Province ofBritish Columbia and Dominion of Canada, have invented a new and usefulStamp-Operating Device; and I do hereby declare that the following is afull, clear, and exact specification, such as will enable others skilledin the art to which it appertains to make and use the same.

The invention is an attachment for machines, particularly of thephotograph printing machine type, which raises the stamping device andinks the numbers, letters, or characters therein each time the machineis operated.

The object of the invention is to provide a means for automaticallyinking the figures, letters, or characters on the numbering stamp ofphotograph printing machines.

Another object of the invention is to provide a device for automaticallyraising and inking numbering stamps as the machine on which the stamp isinstalled operates.

With these ends in view the invention embodies a movable bracket forsupporting a stamp which is constructed of levers pivotally attached toeach other, a spring for so holding the levers and stamp in the downwardposition, a curved arm, which engages a post to raise the stand andlevers, and an ink roller for engaging the stamp.

Other features and advantages of the invention will be seen from thefollowing description taken in connection with the drawings, whereinFigure 1 is a view showing the cover of a photograph printing machinewith the device in place.

Figure 2 is a view showing the device in the downward position.

Figure 3 is a view showing the device in the upward position.

Figure at is a plan view of the device.

In the drawings I have shown my device as it would be constructedwherein numeral 1 indicates any suitable numbering stamp, numeral 2 anink roller, and numeral 3 the main or parallel lever.

The stamp 1 may be attached to the bar 8 by placing the bar through agroove 4 in its upper side and holding it by a pin 5. The bar 3 ispivotally attached to double links 6 and 7 and these links are pivotallyThe spring 11 is arranged so that one end 13 will bear against the upperside of the cover and the other end 1 1 will be placed through a hole 15in the end 10 of the pin 9 as shown in Figure 1. It will be seen thatthis spring will tend to twist the pin 9 in a counter-clockwisedirection so that it will hold the levers and stamp in the positionshown in Figure 2. The opposite end which would be bent to form theprojection 12 as shown will engage a vertical bar 16 as the cover movesupward and as it is forced against the bar it will twist to the positionshown in Figure 3 and move the stamp and levers upward as shown. As thecover moves downward the spring will move the stamp and levers back tothe position shown in Figure 2.

The ink roller 2 is rotatably mounted in a bracket 17 through a pin 18and the bracket 17 is pivotally mounted on the pin 9 and held so thatthe ink roller 2 will have a tendency to move upward by the action of aspring 19 on a bolt 20. It will be seen that the tension on this springmay be adjusted by the nut 21. As the stamp 1 moves upward its lowersurface will engage the ink roller so that it will pass over it to theposition shown in Figure 3. It will be seen that this will be absolutelyautomatic and will work independent of all other moving parts.

It will be understood that changes may be made in the construction,without departing from the spirit of the invention. One of which changesmay be in the type or design of the stamp; another may be in the meansfor attaching the stamp to the bar; and still another may be in the useof a spring of any other type than that shown.

Having thus fully described the invention, what I claim as new anddesire to secure by Letters Patent, is

A device for inking numbering stamps or the like comprising a meansfor raising the stamp; another means for returning the stamp to thenormal position; and an ink roller With a means for resiliently holdingrotatably supported in a, pivoted bracket it :-$1 -fi-P9 -i0. h t th emmp wil endep-m ide nwi iai-mi iem en for P s ey iz I I v hol ng i ee ees eempea ehs p 2.
